UNITED STATES PATENT OFFICE.

JOHN B. ODELL, OF CHICAGO, ILLINOIS.

BATTE RY-ELECTRODE.

SPECIFICATION forming part of Letters Patent No. 327,582, dated October 6, 1885.

Application filed June 26, 1884. Serial No. 136,072. (No model.)

To all whom it may cancela/tf Beit known that I, JOHN B. ODELL, residing at Chicago, in Cook county, in the State of Illinois, a citizen of the United States,have invented a new and useful Improvement in Electrodes, of which the following is a specication.

The object of my invention is to give more strength to the parts of electrodes made entirely of zinc and a cheaper mode of fastening the conductingwires to the saine. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure l is a perspective view of an entire Zinc electrode. Fig. 2 is a vertical section of the stem, showing` the strengthening device. Fig. 3 is a vertical section of the stem, showing the wire and fastening.

Similar letters refer to similar parts throughout the several parts.

Fig. l is the shape and form of the usual entire zinc electrode, having a stem, B, and a base, A, divided into several prongs to give it contact-surface. I find in use the stem is eaten oft' at the point where the air and acid come together before the bottom or pronged part is half consumed, and the bottom is separated so it falls off and breaks the jars,thereby causing a great inconvenience and waste of material. This I prevent by putting in the center of the stem previous to casting a strong wire, S, Figs. 2 and 3, that is not so easily eaten by the acid. This wire is suspended in the mold and the Zinc-poured around it. In case the zinc is consumed at any part of the stem this wire holds the bottom until it is entirely consumed. The wire is made of copper or soft iron, preferably the latter.

In the upper part of the stem of the electrode a hole is made for the reception of the connecting-Wire a. The end of the wire is bent downward, and a key, e, is inserted on the upper side, and its end is bent up so as to keep it in place. It will easily be seen that the wire will not comeout and resist the desired strain. This makes an effectual clamp and gives the wire and electrode a perfect electrical contact. The old way is to put a clamping screw in at the top to bind the wire. My method does away with the screw and makes a large saving in manufacturing.

What- I claim, and desire to secure by Letters Patent, is-

l. In an electrode, asupporting-wire located entirely within the same, substantially as set forth.

- 2. In an electrode, a supporting-wire arranged vertically and entirely within the same, as set forth.

3. An electrode provided with a supporting-core arranged vertically within the same, substantially as set forth.

4. The combination, with the basc having the upwardlyprojecting stem, of a wire 1ocated within the stem and base to strengthen the same, as set forth.

5. The combination, with the base having the upwardly-projecting stem, of a wire arranged within the stem and base to strengthen the same, said wire having its ends bent, substantially as set forth.

6. In an electrode, the combination, with the base having an upwardly-projecting stem, of a wire located within the stem and base to strengthen the same,and having its ends bent in opposite directions at right angles to its body, as set forth.

Signed at Chicago, in the State of Illinois, 6th day of June, 188i.
